The yellow mask is intended to "mask" a child's face, to hide an identity, and to stop gossip..... something it only provokes. The mask itself is a symbol of fear and racism.... a mother who does not wish to expose her own child, the fear of what will happen if her marriage to a black man becomes public, and the fear Effie has of losing her husband. The mask itself is ugly.... it hides the beauty of the child, and it separates the little girl from what could be family. It is a hideous mask that attempts to cover the fear, as well as the mistrust. In the end, Grant is appalled by the mask and completely accepting of Lucy.
